At present, most of them are scanned by medical imaging equipment such as CT, ultrasound or C-arm machine. Based on the principle of the shortest puncture path, the doctor will plan an optimal straight line puncture path before the puncture interventional operation, and then proceed according to experience. Puncture surgery, however, soft tissue is a heterogeneous and anisotropic material. After the puncture needle enters the soft tissue, it will be deflected laterally due to uneven force, causing the needle tip to deviate from the target point, which will affect the treatment effect and lead to long operation time. In addition, Soft tissue is an invisible material, and the deflection of the puncture needle cannot be directly observed after it enters the soft tissue. Moreover, the human body needs to breathe during the puncture process, and the location of the lesion that needs to be punctured may move with the breathing of the human body. The traditional automatic puncture method cannot prevent breathing. As a result, the puncture device cannot accurately puncture the lesion when the human body breathes, whi...

Embodiment 1
[0052] The invention relates to an augmented reality-assisted puncture positioning method, comprising the following steps:
[0053] (1) Select feature points on the model that needs to be fitted, turn on the virtual mixed reality device, and import the model into the virtual mixed reality device; specifically: use the mixed reality device to scan the hand, place a virtual ball at the tip of the finger, Then the finger moves to find the feature points in the space, and records the position, and finally fits;
[0054] (2) Select the puncture entry point, puncture point and puncture channel on the virtual model;
[0055] (3) Import the virtual model into the mixed reality device, and fit the virtual model and the three-dimensional object;
[0056] (4) Binding the identification picture and the puncture needle; specifically: a picture of a two-dimensional code is bound on the puncture needle;
[0057] (5) Turn on the image recognition function in the mixed reality device, start ...
Embodiment 2
[0101] This embodiment is basically similar to Embodiment 1, the difference is that a guide rail is added, in step (8), the guide rail is fixed on the side of the bed, the adjusting rod 8 is adjusted, and the adjusting rod 8 is fixed after the puncture entry point is found, and the rotating button The puncturing track 7 is adjusted to the puncturing direction, and the angle position is adjusted by the fine-tuning device 5, and then fixed for puncturing.
[0102] See Figure 5 , the guide rail includes a fixing device 1, a support rod, a direction adjusting mechanism 3, a direction adjusting rod 4, a fine-tuning device 5, a fixing clip 6 and a clamping device; one end of the fixing device 1 is fixed to the bed through the fixing clip 6, and the other end is connected to the first One end of the support rod 2 is socketed; the other end of the first support rod 2 is rotationally connected with one end of the direction adjustment mechanism 3; the other end of the direction adjustm...

Abstract
The invention relates to an augmented reality assisted puncture positioning method, which comprises the following steps: 1) opening a mixed virtual reality device, importing a mixed virtual model intothe mixed reality device, 2) fitting the virtual model and a three-dimensional object, 3) finishing fitting, and binding an identification image and a puncture needle, and 4) opening a function of identifying the image in the device, (5) after the recognition is completed, emerging a puncture needle model which is the same as the puncture needle, and the two puncture needle models are overlapped;(6) starting puncturing, moving the puncture needle, wherein the puncture needle model in the hybrid virtual reality equipment follows the three-dimensional real puncture needle; (7) confirming the entry point of the puncture needle, and when the puncture needle touches the entry point of the puncture needle, prompting the entry point is confirmed in the equipment; (8) adjusting the puncture direction, and when the puncture direction is correct, it is prompted that puncture is started; (9) when puncture reaches the target position, prompting that puncture is completed; and (10) finishing thewhole puncture process.
Description
technical field [0001] The invention belongs to the technical field of medical puncture intervention, in particular to an augmented reality-assisted puncture positioning method. Background technique [0002] Puncture interventional surgery is a typical minimally invasive surgery, which is widely used due to its advantages of less trauma, less pain for patients and faster recovery. At present, most of them are scanned by medical imaging equipment such as CT, ultrasound or C-arm machine. Based on the principle of the shortest puncture path, the doctor will plan an optimal straight line puncture path before the puncture interventional operation, and then proceed according to experience. Puncture surgery, however, soft tissue is a heterogeneous and anisotropic material. After the puncture needle enters the soft tissue, it will be deflected laterally due to uneven force, causing the needle tip to deviate from the target point, which will affect the treatment effect and lead to lo...
